According to the present invention, also can provide other menus to select in step 401, and/or can omit top some mentioned menus and select.Will with the user in the corresponding storage of the selection during the set handling of step 401 in memory 26.
In step 402, TV-signal receiver 20 is at emergency alert signals, and monitoring is by user's selected frequency during the set handling of step 401.According to exemplary embodiments, the selected frequency of tuner 22 monitoring, thus receive the input emergency alert signals.According to the present invention, TV-signal receiver 20 can be during all operations pattern, monitoring frequency, and receiving emergency alert signals, for example, comprise open, during closing television signal receiver 20 and/or during the playback of audio frequency that has write down and/or video content.
In step 403, determine whether to activate the emergency alert function of TV-signal receiver 20.According to exemplary embodiments, processor 26 is stored in data in the memory 26 and compares and make decision by being included in the data of input in the emergency alert signals and set handling through step 401.As discussed previously, emergency alert signals comprises that expression comprises the type (as cyclone, poisonous chemical leakage, radiation leakage, civil emergency etc.) of emergency and is subjected to the SAME data of the information of the specific geographical area that emergency influences.According to exemplary embodiments, processor 26 with these SAME data with compare from corresponding data set handling, that be stored in the memory 26 of step 401, thereby determine whether to activate emergency alert function.In this manner, have only when by the emergency of emergency alert signals indication corresponding to by the user in the geographic area of step 401 appointment and/or during event type, just activate the emergency alert function of TV-signal receiver 20.
If the decision of step 403 is negated that then handling process turns back to step 402, wherein the selected frequency of tuner 22 continuation monitoring.Instead, if the decision of step 403 is sure, then handling process proceeds to step 404, and wherein TV-signal receiver 20 provides one or more alarm outputs, thereby gives people with emergency notification.According to exemplary embodiments, processor 26 starts one or more alarm outputs according to the selection (that is, project E) of user during the set handling of step 401, and these alarm outputs can be that can listen and/or visual in essence.For example, in step 404, can provide as alarm tone and/or NWS audio message etc. by loud speaker 24 and/or loud speaker 37 and can listen output, and can listen the volume of output to control to these according to user's set volume level during the set handling of step 401.
In step 404, also can provide visual output, to give people with emergency notification by FPD 27 and/or display 29.According to exemplary embodiments,, can provide as showing by display 29 from supplementarys such as NWS text message in certain tones road (for example, showing) and/or video outputs as closed caption in step 404.Equally, in step 404, can provide visual display by FPD 27.The schematic diagram 500 that is used to provide according to the typical technology of visual alert output of the present invention is provided Fig. 5.As shown in Figure 5, supplementary shows that 501 comprise the text message of the details that provides relevant with emergency.Supplementary shows 501 examples just, according to the present invention, also can provide other message (for example, rolling message) and/or display element (for example, icon etc.).Fig. 5 also shows the emergency designator 600 of the part that can constitute FPD 27.According to exemplary embodiments, emergency designator 600 comprises one or more designator elements of the FPD 27 that had before described.
With reference to Fig. 6, show the emergency designator 600 further typical details among Fig. 5.As shown in Figure 6, emergency designator 600 comprises designator element 601 to 604, and visual display can be provided, with just as the information such as mode of operation of the emergency alert function of TV-signal receiver 20, and the information relevant with emergency.As discussed previously, can be the visual indicators of any kind with these designator element 601 to 604 specific implementations, as LED, LCD and/or LQD element etc.For the purpose of example, have four designator elements at the emergency designator 600 shown in Fig. 6.But, this designator element of any amount can be set according to the present invention.
According to exemplary embodiments shown in Figure 6, when the emergency alarm function of TV-signal receiver 20 can be operated and during just at receiving emergency alert signals, designator element 601 can be a green and luminous.Designator element 602 to 604 also can be for different color and luminous, so that the visual information relevant with emergency to be provided.For example, designator element 602 can be yellow and luminous, advises the level alarm with indication.Similarly, designator element 603 can be for orange and luminous, and with the alarm of indication warning level, and designator element 604 can be redness and luminous, with just alarm level alarm.As discussed previously, according to the present invention, these different alarm levels can be represented different emergencies.According to the present invention, also can be provided with except that above-mentioned color other colors and/or with different event flag shown in Figure 6.Therefore, emergency designator 600 shown in Figure 6 is example just, according to the present invention, the designator and/or the demonstration of other types is set also.According to the present invention, also can provide listening and/or visual alert output of other types except that disclosed here in step 404.
In step 405, determining whether provides the time period of selecting in advance with one or more alarm outputs.As discussed previously, the user can specify this time period (that is project F) during the set handling of step 401.If step 405 determine negate, handling process turns back to step 404, TV-signal receiver 20 continues to provide one or more alarms output.Instead, if determining of step 405 is sure, handling process proceeds to step 406, the one or more alarm outputs of TV-signal receiver 20 forbiddings.According to exemplary embodiments, processor 26 outputs are used to forbid one or more control signals of one or more alarm outputs.In this manner, 20 of TV-signal receiver provide time period of selecting in advance by user's defined during the set handling of step 401 with one or more alarms outputs.
After the one or more alarm outputs of step 406 forbidding, handling process turns back to step 402, and TV-signal receiver 20 continues the selected frequency of monitoring, and receiving emergency alert signals.But,, in the section, can not activate emergency alert function once more at the fixed time at identical emergency (that is, repeated events) according to exemplary embodiments.As discussed previously, the user can select the predetermined amount of time (that is, project G) of this repeated events during the set handling of step 401, and different seriousness ranks can be represented different incidents.Therefore, processor 26 is forbidden emergency alert function by user-defined predetermined amount of time at repeating emergency.In this manner, TV-signal receiver 20 will can not provide the alarm output signal at identical emergency once more, till this predetermined amount of time in the past.
As described here, the present invention proposes a kind of can receiving emergency alert signals and provide alarm output with the TV-signal receiver of emergency notification to people.The present invention can be applied to plurality of devices, can have or not have display device.Therefore, here the system or equipment of TV signal can be represented to receive and to handle in employed phrase " TV-signal receiver ", includes but not limited to television set, comprises the computer of display device or monitor and as set-top box, video tape recorder (VCR), DVD player, video game box, personal video recorder system or equipment, the computer that can not comprise display device or other equipment such as (PVR).
Although described the present invention, under the prerequisite that does not depart from spirit and scope of the present disclosure, can further revise the present invention with decision design.Therefore, the application tends to cover variant, purposes or the modification of the various inventions of using General Principle of the present invention.In addition, the application tends to cover the combining of known or customary means in field under the disclosure and the present invention, and it falls within the scope of claims.
